Thanks! I should have clarified that I'm not trying to meet specs for a competition, but rather I'm merely trying to please my taste buds. Also, in years past I step mashed, but now I prefer to do a simple no sparge single infusion. Decoction is out of my league. I don't have suitable equipment for it. I'm mashing in a 52 Qt. Coleman Xtreme cooler with a bag.
I'm trying to achieve a noticeable breadiness. The nearest commercial example to this breadiness is found in Wernesgrüner Pils. I'd like to achieve this breadiness while mashing a bit higher in temperature, using very low mineralization water, and fermenting with White Labs 800 or 802 yeast to get more of a Bohemian style than a German Pils.
